Small, soluble, self-assembling peptide Aβ-oligomers, known as ADDLs
(amyloid-derived diffusible ligands), accumulate in the Alzheimer’s
disease (AD) brain as Aβ 12-mers and are thought to contribute to AD
neuropathological conditions. Unlike plaques, which were once thought
to cause neuronal death due to insoluble amyloid plaque deposits,
ADDLs initiate abnormal changes...
Weak interactions in ligand-receptor
pairs are important in biological systems.
However, the energetics of these interactions
are often difficult to quantify for ligandreceptor
pairs. Weak interactions are a part
of reorganization energy, which plays a role
in electron transfer reactions. Under certain
conditions the rate of electron transfer
